Recommendation G. 729.1 is a new ITU-T standard which was approved in May 2006. This
recommendation describes a hierarchical speech and audio coding algorithm built on top of …

In this paper, we propose a new statistical enhancement system for throat microphone
recordings through source and filter separation. Throat microphones (TM) are skin-attached …

Quality and intelligibility of narrowband telephone speech can be improved by artificial
bandwidth extension (ABE), which extends the speech bandwidth using only information …

In this paper, we propose a hidden Markov model (HMM)-based wideband spectral
envelope estimation method for the artificial bandwidth extension problem. The proposed …

(57) ABSTRACT A system for transmitting data packets representing a source signal across
a packet data network is provided. The encoder comprises a first encoder (110) and a …

We investigate spectral envelope mapping problem with joint analysis of throat-and acoustic-
microphone recordings to enhance throatmicrophone speech. A new phone-dependent …

Voice conversion methods have the objective of transforming speech spoken by a particular
source speaker, so that it sounds as if spoken by a different target speaker. The majority of …

The throat microphone is a body-attached transducer that is worn against the neck. It
captures the signals that are transmitted through the vocal folds, along with the buzz tone of …

Quantization of a probability measure means representing it with a finite set of Dirac masses
that approximates the input distribution well enough (in some metric space of probability …

Automatic speech recognition (ASR) is a task of converting speech to text. In this article, the
ASR system trained using the speech of adult speakers and tested using the speech of child …
